Well YMMV, could have been weak mag springs not keeping up, but it ran fine on normal pressure loads. Why beat up the gun just for a few extra fps? If you want more oomph, get a bigger caliber.
If you have a modern 9mm pistol that doesn't run on +P, it's probably time to get a better pistol.
+P rounds don't beat up any of the modern quality defense-suitable pistols I am aware of. Certainly not in the kind of volume they are going to be shot by almost anybody who is using them defensively...especially considering what it would cost to buy thousands upon thousands of rounds of +P Gold Dot/HST/whatever.
Get a bigger caliber? Why would I want to spend significantly more money on ALL ammo and have reduced capacity?
I assume you are aware that there is nothing special about +P, right? It's really more that some cartridges, like 9x19, have been around so long, that it is not recommended or necessarily safe to shoot the same ammo out of a many decades old gun as it is a new, modern, quality gun. It's not like shooting +P rounds through your modern Glock/Sig/Springfield/S&W/H&K/Walther/whatever is akin to putting a bottle of N02 through you mini van or anything lol
You claim hydra-shock is an outdated bullet design (yes the HST is newer), but then you recommend 9BPLE, which is the REALLY old Hi-shok from the 80's. Ok then.
Yes. I do. Why? Because 9BPLE has a stellar track record from all levels of US law enforcement (federal, state, local) that cannot be written off, and it can be had for significantly less money than the best stuff, so if you are budget conscious, it is the way to go. Mas Ayoob, as it happens, says 9BPLE is in the top-5 defensive loads, currently, for 9x19.
Sometimes you can get really good prices on SD JHP in bulk purchases online once you find the load your gun likes. And every few months I will shoot off the ammo that's been carried to make sure the gun still likes it and then reload with fresh ammo that hasn't been exposed to humidity or condensation going from cold to warm temps.
Gold Dot and HST only gets so inexpensive. It is never available for the type of deal you can get on 9BPLE.
I would definitely recommend Gold Dot or HST or similar if one can afford it and justify the expense, but if one wants to spend less/shoot more of it, 9BPLE is the answer.
